MMO coated tubular string anode are used to protect the pipe lines which is installed horizontal bed as well as vertical deep well with multi string /single string based on several design and field condition factors including current distribution requirements for different application like Sea water, brackish water, sand etc.,

These anodes connected to a DC power source, often a transformer-rectifier connected to AC power. In the absence of an AC supply, alternative power sources may be used, such as solar panels, wind power or gas powered thermoelectric generators. These tubular anodes are used to protect the pipelines from corrosion and rust.
